ROLLER BEARING.

application med march 1s, 1922. serial no. 544,856.

To all whom coment:

Be it known that I, LYMAN W. CLOSE, a citizen of the United States, and a resident of Toledo, county of Lucas, State of Ohio, have invented certainnew and useful Improvements in Roller Bearings, vof which the following is a specification.

This invention `relates to anti-friction bearings and more particularly to cages for roller bearings for retaining fthe rollers in assembled relation with the cone of the bearing.

One of the objects of the invention is to provide a cage of comparatively simple construction whichl can be manufactured economicallyy from a flat piece of steel and which lwill possess the requisite characteristics of durability and strength.

A further object of the invention is to provide a cage which will be constructed of a single piece of metal without joints and weak parts. l,

Other objects of the invention and the features of novelty 'will yapqjnarent from the following description taken .in connection lwith the accompanying drawings, of which: i y

Figure 1 is a i.transverse section of a, metal blank from whichfa. cage embody i the invention is formed;

igs. 2 to 6, inclusive, are transverse sec l tions ofthe cage in different stages of manufacture;

'Fig'. 7 is a-transverse 7-7 of Fig. 6;

Fig. 8 is a view similar to Fig. 6 but showing the next operation in forming the cage;

Fig. 9 is a transverse section of the cage indicating the method of assembling the rollers and the cone therewith;

Fig. l() isa view similar lto' Fig. '9 but indicating the completion of the assembling oper-ation: and

Fig. 11 is an enlarged transverse section of a fragment of' a bearing embodying my invention` Referring to that the cone 20 is lrovided with theiend flanges 21 and 22 wliieh serve to limit the endwise movement of the rollers 23 and co-operate with the cage, which will now be described, to retain-the rollers .in as# sembled relation with the cone 20. In Fig.

section on the line Fig. ln n Win be Observed .'11 the cup of the bearing is vindioated ,at

`The cage comprises the end flanges 25 and. 26, one turned outwardly and the other turned inwardly and being connected by brdgingmembers or spacers 27 between the rollers. The bridging members 27 have arranged on their-'opposite longitudinal edges the wings 28 which partially surround the willbe readily understood, by those skilled in .the art, from 'an inspection of Fig. 2. Tlhe next operation is tore-strike the fcu'p, as shown in Fig. 2, tothe form indicated in Fig. 3 in which the corners 29 and 30 are squared up and reishaped. By the succeeding operation the opening 43]. is punched in the bottom of the ange 25 is trimmed to size.`

The opening .3l is t0 receive thev arbor cup andthe of an'indexing fixture which is employed in .l

the next operation which consists in punching the roller openings 32. In Fig. 5 I have onlyindicated some of the openin s 32 but it will be understood that therewill be one such opening formed in the cage for I each of .the rollers.

The' next opration is" indicated 1n Figs. 6 and 7 and consists inf throwingthe wings 28 outwardly and shaping them to conform lto the tapeed surfas of the rollers when the latter 'are assembled in the cage. By the following operation the .bot-tom 33 is punched out, leaving the. nturned flange 26.

The rollers are' then placed in the cage from the interior,' the shape of the cage permitting them to assume apprdximately Jche position indicated by the roller 23 in' Fig. 9. vWhen all they rollers are in theirA places the cone 20 is inserted, the vsmall ends of the rollers being spaced apart sufliciently to permit the flange 22 on the cone to freely pass, the cone assuming the position indicated in Fig. l0. v

The opening for the roller is of a peculiar shape and adjacent the bottom of the cage is narrower than the diameter oi the roller et its small end While at the larger end of the roller it is slightly in excess ot the diameter. i351 this construction the roller is held in position in the cage, the larger end being retained by the Wings 28.

The final operation in assembling consists in pressing the bridging members Q1? inwardly at the point adjacent the smaller ends of the rollers, thereby eliminating the bend in the bridging members at this point. :is will be seen from Fig. l0. ln this operation the lange 25 is also turned down slightly and the smaller ends of the rollers are carried inwardly against the rolling' surface oi the cone 20 and the latter is thereby locked in its assembled relation with the cage and rollers.

IAG

The outer surface of the head of the roller contacts with the inne1` face 35 ol the flange 2l of the cone and7 in the final closing;r operation, the cage will be so held that the end 36 ol the roller openings will be in substantiel contact with the outer surface of the roller heads. By properly shaping the Wings 28 and regulating' the final closing operation, which eliminates the bend at the point 3% in the bridgino members, the rollers will be closely confined in the cage by the Wings and the ends 36 of the roller space-s. rlhis Willinsure accurate concentricity. of the cage with the axis of the bearingr and also prevent disalignment. of the rollers, therebj, providing a construction that will be especially well adapted A,tor heavy loads and relatively high speeds.

lfyf melting' the cage oi a relatively heavy gauge ol metal and proportioning the parts es indicated in the drawings e structure ol' unusual strength is provided. lt will be noted that the wings 28 are of substantiel@` triangular forni, being` Widest adjacent the leren' end oi.' the roller end tapering to nothingadjacent the smaller end of the rolle-i.; this 'form providing adequate surlfsce for Contact with the rollers which minimizes the Wear and :lids in the lubrication of the bearing` when in service.

HavingT thus described my invention, what l claim isz l. A cao-e -tor roller bearinfrs comprising;F cnil flanges end roller spacing bridgringn members connecting said end flanges and so formed :is to lea-ve roller spaces each or which :it one end is ol' less width than the diameter orL that part of the roller that tits therein, and at the opposite end is as Wide as the diameter of that part ot the roller that lits therein, each of said bridging members having wings along its edges adapted to partially surround the rollers to retain the latter in seid spaces.

2. A cage for roller bearings comprising .end flanges and roller spacing bridging members connecting with the inner edge of one of said end anges and with the outer edge of the other of said end members end so formed as to leave roller spaces eech ot. which at one end is ot less Width than the dia-meter of that part of the roller that ts therein, and at the opposite end is as wide as the diameter ot' that part of the roller that fits therein, each of said bridging members having Wings along its edges adapted to partially surround the rollers to retain the latter in said spa'ces.

3. ln roller bearings the combination of a. cone having anges at its opposite ends and the rollin surface for the rollers therebetween, a series of circumferentially spaced rollers on said surface and a cage for retaining said rollers properly spaced and in assembled relation with seid cone comprising end flanges and roller spacing bridging members connecting said end flanges and so formed asto leave roller spaces each ot which atpne end is of less Width than the diameter of that part of the roller that fits therein, and at. the opposite end is as Wide as the diameter of that part of the roller thst tits therein, each of said bridging niembers having Wings along its edges adapted to partially surround the rollers to retain the latter in said spaces. Y

4. in roller bearings, the combination of en inner race member,. eli/series of cireum' terentially spaced rollers assembled -with said member and e cage for retainingl said rollers properly spaced'end in assembled relation with said member comprising end `flanges and roller-splicing bridging members connect-ing seid end llenges and so formed es to leave roller spaces each of which at one end is of less Width than the diameter of that partei the roller that lits therein, each ot' seid bridging members having Wings along the edges adapted to partially surround the rollersi and one of said end hannes being in substantial contact with the with seid wings to closely confine the rollers y in the said spaces and hold the cage in substantiall7 concentric vrelation to said inner member.

ln testimony whereof l ehx my signet-nre,

LYMN'W, CLSE.
